Application filed April 18, 1922. Serial No. 555,136

To all whom it may concern:

Be it known that I, GUSTAV Nnrrz, a citizen of the United States, residing at Richmond Hill, in the county of Queens and State of New York, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

This invention relates to heaters, particularly to that type in which gas is used as a fuel, the main object being the provision of a heater which has baffle plates arranged in a manner which will give a maximum amount of a heat from a given amount of fuel used.

Another object is to provide a heater as described, the interior thereof being designed so that the device will emanate heat in all directions so that an even temperature may be maintained in a room without having to move the heater from place to place.

These and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing; Figure 1 indicates a front elevational view of the same showing part of the body in section.

Figure 2 is a side elevational view of the heater, the upper portion being broken away to disclose the interior.

Figure 3 is a perspective view of the heat distributor.

Figure 4 is a cross-sectioned plan view pivot lugs 16 at its lower end, between which a draft door 17 is mounted, is secured to the side walls 12 1n a suitable manner.

A cover member 18 having turned down edges 19 which are receptive of the extending flanges 20 of the body walls 11 and 12 and the front 15 is secured in place on the body by knob headed corner pieces 21.

A flanged bottom plate 21 is secured within the lower end of the body and seats brackets 22 in which a fuel distributor 23 is mounted. The latter is provided with a plurality of radially disposed jets 24 through which the fuel gas passes from the feeder pipe 25 to thepoint of ignition. The

usual mixing head 26 is provided at the junction of feeder pipe 25 and'distributor 23. A valve 27 is also provided at this point so as to regulate the fuel'supply desired.

A heat distributor composed of a unit piece of metal, preferably of fire resisting material, is formed into front and rear walls 28 and 29 respectively and side walls 30.

The corners are provided with extending guide lips 31 which snugly fit the corners of the body and prevent the heat distributor from moving about in the main body.

A convexly curved radiation hood 32 in guides said heat waves to the front and rear walls to emerge into the atmosphere through longitudinal ports 35 and the heater vents 36.

In using the heater the tapered nose 3? is connected to a gas pipe by a flexible tube, which will permit the same to be readily moved about. Door 17 is then opened and valve 27 is also opened so that'the escaping gas will be readily ignited by a match.

Said gas flame will come from the ports 24 c and will radiate upwardly through holes 32 and out through vents 35 and 36. It is to be noted that the heat distributor may be readily replaced by removing the cover 18 which can be easilyaccomplished by first removing front wall 15.

It is to be understood that certain changes I in form or construction, such as replacement of the gas fuel feed with'an electrical coil, may be made without departing from the spirit and scope of the invention.

I claim;

1. A device of the class described comprising an outer body, a detachable front wall on said body, a hinged door pivoted at the lower end of said front wall, a bottom secured in said body, a fuel distributor pipe mounted thereon. a. cover member secured to the upper end of said body, a heat distributor seated on said bottom and having openings at its lower end and means mounted Within said distributor for concentrating the heat Waves and means for distributing the same at the upper port-ion of said body.

2. A device of the class described co1nprising an outer body, a detachable front wall on said body, a cover member surmounting the body and securing the front Wall in place, a hinged door at the lower end of said front Wall adapted to regulatethe circulation of air, a fuel distributor pipe mounted Within the body, a heat distributor 'insertable in saidbody when the cover and front is removed, a concavely curvedplate secured to the lower portion of the heat distributor having .a plurality of vents adapted to transmit and concentrate the heat Waves passing therethrough, a convexly curved plate at the upper end of said heat distributor, said convex plate forming passages at its side and further adapted to bafv fle the concentrated heat Waves and distribute the same through said passages and a valve for controlling the flow of fuel.

In Witness whereof I, affix my signature.

GUSTAV NIETZ.
